So you can breath less and get more by breathing through the nose. - James Nestor

[R]esearchers... were a bit frustrated... seeing so many chronic conditions ties to mouth breathing, and how so many... could either be improved or... cured by switching the pathway in which you breath.

I went to Greece to write a story on ... When most people go underwater... they bail out at ten feet... ears screaming. The freedivers told me they'd previously been "most people." ...To freedive, they said, all anyone had to do was master the art of breathing.

I read through reams of literature on the subject. ...The problem was, the sources were hundreds, sometimes thousands, of years old.
